DONALD JOHNSON, OF WEST SUPERIOR, WISOONSIN.

DOOR.

SPECIFICATION forming part of Letters Patent No. 437,438, datedSeptember 30, 1890.

Application filed March 12, 1890. Serial No. 343,583. (No model.)

To all whom it may concern:

Be it known that I, DONALD J OHNSON, a citizen of the United States,residing at West Superior, in the county of Douglass and State ofWisconsin, have invented certain new and useful Improvements in Doors;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in-theart to which it appertains to make and use the same.

My invention consists in a new and improved folding door, which isformed of sections hinged together on Vertical lines and suspended atit-s upper edge, so that the door can be folded back flat against thejamb of the door-casing, thus obviating the necessity of providing aspace between the walls for its reception.

My invention will be hereinafter fully described and claimed.

Referring to the accornpanying drawings, Figure 1 is a side view showingmy new and improved folding door partly opened. Fig. 2 is a top planview of the door and the track on which it is supported. Fig. 3 is adetail view of one of the swiveled castings which support the door, andFig. 4 is a detail view of a section of the track on which the saidcasting runs.

The same letters of reference indicate corresponding parts in all thefigures. p

Referring to the several parts by letter, A indicates the door-frame,which is here shown in connection with my folding door. The top of thisframe is formed with the central longitudinal slot B. The door proper isformed in three Vertical Sections C O' C2, although it may be formed ofany desired number of sections. These sections are hinged at theirmeeting edges, as shown, and the rear section C2 is hinged to the doorframe 01' jamb in the usual manner.

To the top of the door-framing are secured the longitudinal tracks D D,each of which is formed at its inner edge with the longitudinalupwardly-projecting flange D' the tracks being secured at each side ofthe central slot B, so that their inner-edge fianges project up in thesaid slot, as shown.

On one side of the upper end of each doorsection is bolt-ed anangle-plate E, the upper end of which extends over the upper edge of thedoor, and through this upper part E' of It will thus be seen that thedoor-Sections are supported at their upper ends on the tracks D by theswiveled castings, and when the door is to be opened, it is pushed back,as shown in the drawiugs, when the fianged castings G will slide freelyupon the fianged tracks D, the pivots or swivels F in the upper ends ofthe door-Sections turning freely and easily in the castings G,preventing all possibility of binding. The door thus slides back easilyand folds flat against the doorframe, where it is out of way, occupyingbut little room, and it can be as readily closed again.

From the foregoiug description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of mynew and improved folding door will be readily understood.

It will be seen that myinvention is simple and strong in construction,that the door occupies an extremely small space when folded, and that itcan be employed where there is no room for forming a space between thewalls for the reception of the old style of sliding door, It can bemanufactured at a comparatively small cost and for any size openiugs, orfor single or double doors.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The combination of the door formed of the hinged sections, theangle-plates secured to the upper ends of the said Sections, the swivelsF, the castings G, formed with the parallel downwardly-extendingedge-fianges, and the track-plates having the longitudinalupwardly-extending fianges at their inner edges, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.

DONALD JOHNSON.
